# 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.
