+# MiniPill LoRa Board
+Here is general information on the (PlatformIO) settings for the MiniPill 
+LoRa boards. The files on this repository are placed in ~/.platformio. 
+Where ~/ is your home directory. 
+
+These settings are used on macOS platforms with user leo.
+Please changes the files for your OS/user.
+
+## version 2022-12-24
+Created develop branch where other boards with other microcontrollers are 
+available and tested. Removed them from main branch. Only the 
+STM32L051C8T6 and STM32L151C8T6 version is present at the main branch.
+
+## versions 2022-10-23
+- ```PlatformIO Core, version 6.1.4```
+- Initial setup of this repository
+- Removed board information from MiniPill LoRa LMIC project and moved to 
+this repository
+
+## Board versions
+There are different version available 1.x, 2.x, 3.x. All versions use the 
+same electronic schematic. Only the PCB layout and/or antenna connector is 
+different. 
+
+## Two types of processors supported
+In the boards directory are a two major types and some test boards, please 
+ignore them.
+
+The Orginal MiniPill LoRa with STM32L051C8T6
+
+```minipill_l051c8_lora.json``` variant dir: ```MINIPILL_L051XX_LORA```
+
+For testing with STM32L151C8T6
+
+```minipill_l151c8_lora.json``` variant dir: ```MINIPILL_L151XX_LORA```
+
+
+## Adding a custom board in PlatformIO
+To work with the MiniPill LoRa in more than one project you should add 
+this custom board to you PlatformIO toolset.
+On MacOS under the user's homedirectory a .platformio directory is 
+available for the toolsets. This is the platformio homedirectory. Please 
+check for your OS where this directory is located.
+
+- copy the *boards* and *variants* directory from customboard directory to 
+the ```.platformio``` directory
+- change the absolute path in the boards/minipill_l051c8_lora.json file 
+for the variants path
+- restart platformio/IDE
+
+Now you should be able to use the MiniPill LoRa board in a new project.
+Not all functions are tested with this custom board configurations.
+
+## debugging
+I use the hardwareSerial for debugging and connected a serial TTL-USB 
+converter. This will take some power in Low Power mode.
+
+## Clock Settings
+The clock settings for this custom board are set in the
+`.platformio/variants/MINIPILL_L051XX_LORA/variant.cpp` file. In the `WEAK 
+void SystemClock_Config(void)` function the HAL functions are called to 
+select the clocks.
+For use of I2C and 100kHz clock signal you have to change these settings 
+in:
+
+```
+	WEAK void SystemClock_Config(void)
+	{
+	  RCC_OscInitTypeDef RCC_OscInitStruct = {};
+	  RCC_ClkInitTypeDef RCC_ClkInitStruct = {};
+	  RCC_PeriphCLKInitTypeDef PeriphClkInit = {};
+
+	  /* Configure the main internal regulator output voltage */
+	  __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);
+
+	  /* Initializes the CPU, AHB and APB busses clocks */
+	  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_MSI;
+	  RCC_OscInitStruct.MSIState = RCC_MSI_ON;
+	  RCC_OscInitStruct.MSICalibrationValue = 0;
+	  RCC_OscInitStruct.MSIClockRange = RCC_MSIRANGE_5;
+	  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE;
+	  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) {
+	    Error_Handler();
+	  }
+
+	  /* Initializes the CPU, AHB and APB busses clocks  */
+	  RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK | 
+RCC_CLOCKTYPE_SYSCLK
+	                                | RCC_CLOCKTYPE_PCLK1 | 
+RCC_CLOCKTYPE_PCLK2;
+	  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_MSI;
+	  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
+	  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV1;
+	  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;
+
+	  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != 
+HAL_OK) {
+	    Error_Handler();
+	  }
+	  PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_USART1 | 
+RCC_PERIPHCLK_USART2
+	                                       | RCC_PERIPHCLK_I2C1;
+	  PeriphClkInit.Usart1ClockSelection = RCC_USART1CLKSOURCE_PCLK2;
+	  PeriphClkInit.Usart2ClockSelection = RCC_USART2CLKSOURCE_PCLK1;
+	  PeriphClkInit.I2c1ClockSelection = RCC_I2C1CLKSOURCE_PCLK1;
+	  if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit) != HAL_OK) {
+	    Error_Handler();
+	  }
+	}
+```
+
+You can also **add this function to you main code** and call it in the 
+first line of the setup function of your Arduino main program. Do not use 
+the WEAK compiler direction.
+
+When you must use a higher clock rate you should use the HSI clock. In my 
+experience this is necessary when using OLED displays with I2C 
+communication.
+
+The function for 400kHz clock rate is:
+
+```
+	void SystemClock_Config(void)
+	{
+	  RCC_OscInitTypeDef RCC_OscInitStruct = {0};
+	  RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};
+	  RCC_PeriphCLKInitTypeDef PeriphClkInit = {0};
+
+	  /** Configure the main internal regulator output voltage
+	  */
+	  __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);
+	  /** Initializes the RCC Oscillators according to the specified 
+parameters
+	  * in the RCC_OscInitTypeDef structure.
+	  */
+	  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;
+	  RCC_OscInitStruct.HSIState = RCC_HSI_ON;
+	  RCC_OscInitStruct.HSICalibrationValue = 
+RCC_HSICALIBRATION_DEFAULT;
+	  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE;
+	  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
+	  {
+	    Error_Handler();
+	  }
+	  /** Initializes the CPU, AHB and APB buses clocks
+	  */
+	  RCC_ClkInitStruct.ClockType = 
+RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
+	                              
+|RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
+	  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_HSI;
+	  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV8;
+	  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV1;
+	  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;
+
+	  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != 
+HAL_OK)
+	  {
+	    Error_Handler();
+	  }
+	  PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_I2C1;
+	  PeriphClkInit.I2c1ClockSelection = RCC_I2C1CLKSOURCE_HSI;
+	  if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit) != HAL_OK)
+	  {
+	    Error_Handler();
+	  }
+	}
+```
+
+Remember that the change in clock settings will affect power consumption! 
+You can generate you own clock settings by using STM32CubeMX or 
+STM32CubeMXIDE configurator. Copy the `SystemClock_Config(void)` function 
+generated by the configurator.
