Latency in scanning with reader. Board ST25RU3993
I'm having issues with using the SDK of ST25RU3993. Specifically, while reading tags, I seem to get too much of a latency.I have went through the header files, but don't seem to find the appropriate variable.Currently each RFID scan takes about 24 s...
storing string's on flash
hi,I initialized string array with strings and type cast to uint32_t to store in flash memory as uint32_t. And then read the array as uint32_t. I update one of the string of the array and type cast uint32_t to store that array in Flash memory back. ...
problem reading data from SCD30 with NUCLEO-L476RG
I am having issues with reading data from the SCD30 CO2 sensor. every byte of data I get back is 0xDD (or 221). I am still learning so my methods may be questionable. If anyone can help narrow down why this is happen and how to fix it, I would be ver...
STM32F412 CAN Transmits unexpected data
When I trigger a transmit of a test CAN message on CAN bus 2 the CAN module transmits unexpected data when I look at CAN bus with a logic analyzer. PCAN does receive the unexpected message and it does acknowledge the massage. Here is what I see on th...
FDCAN wakeup from stop mode in STM32H733
Hi,I'm trying to wakeup the mcu from data coming in FDCAN1 to FDCAN3. Is it possible?I know that with UART I can use this function : HAL_UARTEx_EnableStopMode().Is there a similar function to do the same thing?If i can't is it possible to make 2 pins...
Resolved! Why does 'G0 ADC Calibration in Cube/HAL perform averaging in software?
The STM32G0 ADC calibration in Cube/HAL performs 8 iterations of the calibration process, each time reading out the calibration factor and accumulating it, then dividing by 8 (i.e. taking their average) and writing it back to the calibration factor h...
Resolved! UART with STM32F405
I am having some issues with setting up the UART for my STM32F405RGT6. I have a custom PCB which has an CH340C (U7) serial chip and a USB-C (U1) port. See wiring diagram:I have set up my project in STM32CubeIDE and have connected to my MCU with a ST-...
Resolved! HRTIM interrupt callback function
I would like use HRTIM timerA interruption event, so I where looking for the weak function to rewrite it but not found it.I found that I must set compilation flag USE_HAL_HRTIM_REGISTER_CALLBACKS to 1 and make all functions as weak. If I make so stro...
Resolved! Trigger from Timer does not trigger injected conversion on ADC
JEOC nor JEOS triggers an interrupt. I already made sure that the ADC and the interrupt itself are working. (Regular conversion start by software).Tried both trgo2 of timer and CC4 of timer to connect the adc with, which both did not work.CCR4 is sma...
