Posted on August 28, 2017 at 18:08Hello everyone,I am having a bit of trouble with the SPI communication between two STM32L053R8 boards.I have a master who is sending 15 bytes every second to the slave. The slave must also return 15 Bytes.Tha maste...
Unfortunately, I wrongly designed the PCB board So, the boot0 pin is currently floating (no connectable evenif temporaliy because of BGA pin layout).I'm getting trouble with programming. So, I want to know whether the programming error is happening d...
I have been stuck on a tricky little issue for some time now.Using an STM32H753, on a reasonably large and complex application, when trying to erase the upper flash bank, the watchdog expires resetting the chip!My suspicion is that the CPU is stallin...
Hi, we use 12 ADC channels to measure temperatures in a smart home project. The system clock of the STM32F071V8Tx is configured at 48 MHz. Due to the slow temperature curve, we use the longest sampling time. We have taken a conversion table from a da...
I was reading the documentation from: https://www.st.com/en/embedded-software/x-cube-eeprom.html#documentationabout the eeprom lib. Concerning the cleanup time, I don't follow where the number comes from. I am using an L4 and there was only one examp...
Hi I come across an ADC code as below, could anyone advise whats the meaning of pointer *h in the function argument and whats (h = &hadc1) do inside the callback function ?main(void){ HAL_ADC_Start_IT(&hadc1); ... while (1) { if (adc_valid ...
Dear Experts,I have 4 inch RPI LCD 480x320 SPI based on the ILI9486 display driver. Like inside ArduinoIDE, there is a Library manager where we can find so many TFT-LCD libraries with STM32 board support, Is there a common place to find libraries for...
how does fmc work does it use spi?
Is the maximum APB frequency setting 36MHz or 50MHz? See the dm00031020, page 863. FREQ[5:0]: Peripheral clock frequency..."Higher than 0b100100: Not allowed"0b100100 corresponds to 36MHz, not 50MHz. Hopefully this is just a document error. We are us...
