I've got a STM32L053 (on a Nucleo-Lo53R8). I'd like to drive TIM21 from the 32KHz clock, and gang it with TIM22 to form a 32 bit counter. But I'm confused on a few points.First question: how to drive TIM21 from 32KHz? The documents (RCC chapter, 7.2....
The problem is as follows: When I am trying to update HRTIM master timer registers (MPER, MCMP1-4) on the STM32G474 via Burst DMA access, every data word I write into the BDMADR register gets written into two of the specified master timer registers. ...
I came across a problem exactly described by this erratum: As you can imagine, this was "fun" to investigate.You may ask, "But Jan, don't you know you should read the Errata first?". Problem is, this is ES for 'G0B1, whereas the problem was observed ...
I was working on a simple SPI transmit code, I am transmitting some string data via SPI Half duplex, the code is like I press blue button on the discovery board, and it transmits data, which I read from logic analyzer, but every time after data is tr...
The function is supposed to read the I2C in non-blocking mode.However - quite often - it blocks the MCU for like 2 seconds!As I need to read an I2C in time critical part of my program, this breaks everything.I investigated the function source and I f...
I have read a book on stm32, and inside the timer topic, it is stated that a formula to determine the values to be loaded to generate interrupt at specified times which as below:My question is does this formula applicable for all stm32 timers? and an...
Hello all, I am currently trying to get my STM32F411RE code working in Atollic TrueStudio. This project leverages the use of DMA and CMSIS-DSP which are all working in TrueStudio to find freqeuncy outcomes. The issues at hand is that I can upload my ...

Hello everybody!I am looking into possibilities of having 256 megabytes of SDRAM memory on a 144 pin STM32F7 chip. As I understand the 144 pin chips only have 16 bits data bus available for the SDRAM interface, so I was looking into using two, 8 bit ...
