Board resets systematically from standby mode
Hello,I would like to reach the lowest consumption as possible. I am programming an end node which sends data through TTN. My project is based on the LoRaWAN End Node example with the LoRaWAN middleware. My fimrware works like that :at boot, the boar...
Resolved! STM32WL5MOC no transmit
Hello,I have developed a breakout board for the STM32WL5MOC for development purposes and it uses both rf switches and the wiring is identical to the B-WL5M-SUBG1 evaluation board.Running the B-WL5M-SUBG1 sample application SubGhz_Phy on my board and ...
communication with sensor: scd41-d-r2
Good evening, I ask for help regarding the communication between stm32wb5mmght6tr and the scd41-d-r2 sensor. I connected the sensor to pins PC0 (SCL) and PC1 (SDA) and powered the sensor but after loading the code I attach, the i2c communication give...
Not receiving bytes correctly in LPUART with STOP2 mode on STM32WB55RG.
I am trying to implement MODBUS slave on custom board with WB55 on low power mode and need to support 9600, 19200, 57600 and 115200 baud rates.As a first step, I tried to receive 8 bytes of MODBUS command on LPUART and send it on USART1 with HAL with...
STM32WL55CJ1 Problem with C1IMR1 register
I am having an issue with configuring the C1IMR1 register, I created test code for enabling interrupts on the user buttons on the stm32wl55cj1 board but the C1IMR1 register is not being set. Below I will attach the code.
stm32wle5 - internal clock derivation for LPUART
Hi, I work with stm32wle5 where AT commands are received from LPUART. This interface is setup for 9600 bps / 8N1 and its baudrate clock is derived from LSE (32768Hz) clock. The chip is wake up by incoming characters. I observe that transmitted bits h...
Choosing ADC Reference Voltage
Hello, My problem is that I have a custom STM32WB55RG board and I want to use ADC reference voltage as 1V or as close as possible to 1 V. My questions are:1- In datasheet, it states that "If VDDA> 2V, it should be 2<Vref<VDDA and if VDDA<2V, Vref sho...
