How Best To Buffer/Receive This UART Data?

I need to receive a six-byte packet via the UART (using an STM32L010F4). There is a SOF and an EOF byte included in these six bytes. There could be long stretches when no data is sent, followed by a stream of these six-byte packets that are 5mS apart...

I just updated STM32CubeIDE from version 1.5 to 1.6.1. Now some of my math function calls are no longer working - such as pow(). The compile error I receive is : argument 6 of ‘__builtin_tgmath’ is not a function pointer. What has changed?

Half duplex SPI 8 bits on STM32G491VCTx

Hello,For one of my projet, I need to use a Half Duplex SPI line in 8 bits in order to communicate with a sensor.When receiving the data, the sensor need a certain amount of time between each group of 8 bits, so I can't just use a 16 bits line.I trie...

How to run code without power cycle after programing a virgin STM32L4xx over i2c without touching reset or boot0 pin?

The bootloader starts automatically on a virgin STM32L4xx MCU without putting boot0 as flash is empty. I can then flash it over the i2c bus but is unable to get the code running without power cycle.I have tried, software reset, hardware reset and run...

STM32H755BIT DMA2D + FMC + External SRAM Write Issue

I am using the DMA2D to transfer colour data to an external SRAM using the FMC with an 8-bit parallel hardware setup. I can use the following line of code on the CM7 CPU to write to any in-range address (0x68000000 base) with any pointer type (uint8_...
