Hello to the forum. I would like to start working with stm32wb55, due to its low consumption and also because it has the BLE protocol. However, I cannot find how to implement and link the cpus. I ask if anyone knows where I can get simple and practic...

Good afternoon to all forum members. I have a problem with stm32wb55 and i2c protocol. I use i2c (hi2c3) with the connected peripherals Ad7746, adxl345, mcp9808 and they work fine, but if I join fram MB85RC256v, with the write/read in the routine I w...

I need to make a device that communicates (modbus) with a product that uses the rs232 protocol, with 7 bits and 2 stop bits. I use CubeMx and HAL libs. There is some process to do this. As is known in STM32, only have 8 and 9 bits in length.

From the research I did, I noticed that the problem with i2c in the stm32wb family is not new. Happens with HAL_I2C_Mem_Write(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData, uint16_t Size, uint...

Petr DAVID, thank you for the information. I will be watching the course.

Hello everybody.I experimented with the code on a stm32f103 and it works, as it writes and reads the eeprom/fram. The same code written in stm32wb, doesn't work. Don't want to think it's a bug!? I would appreciate if anyone had the same problem and w...

Thank you again Clive Two.Zero for your response.It's working

Thank you Clive Two.Zero for your response. I think DR (reading / writing) means date? But what's the setup on CubeMx? 8bits N 1 or other option.Thanks for the informationBravos

How to implement a a BLE, with a sensor in the MCU STM32WB55

Fram write/read error, with stm3wb55?

stm32f103c8t6 rtc. When I restart the power supply, I lose the date, but the time is correct (Keil),

It will be possible communicates with 7 bits + 2 stop bits, in Stm32f103c8t6?

Stm32f103c8t6 TIM1, where 1ms is mandatory. I need a Ticker of 0.01ms or 0.001ms, to be able to discount with the time of the routines to increment / show the time in a serial display / 32bits. Bravos
