Resolved! How to manage chip select pins when reading/writing SD cards on an SPI master/slave(multiple) configuration ?
Hello, I have succeeded in accessing (r/w) an SD card with STM32F103C8 blue pill and a microSD adapter using SPI in a master/slave configuration. Now I want to go to the next level by using 2 SD cards in a master / multiple slave configuration.Accor...
Voltage reference buffer output does not match expected value?
Device: STM32G061 (custom board), system running at 8mhz.I set the vrefbuf mode to Internal voltage reference mode in cubemx. According Scale 0 the expected output on Vref pin should be 2.048V but the value i measured was always 0.2-0.3V greater than...
Resolved! STM32H743 ADC/DMA apparently skipping samples
I have a set up where I'm reading from ADC1 via DMA1 S0 into a circular buffer in RAM2. The problem is that it is randomly skipping samples. I initialise the buffer to a known bad value so I can see that some addresses in the buffer are not being ove...
Port of X-CUBE-PLC1 for STM32L476
Hi everybody! I just bought my first board (NUCLEO-L476RG) to start playing.I succeded in my first program making LD2 LED blink upon pression of B1 button.Now to go one step further I bought an X-NUCLEO-PLC01A1 board to interface to some "standard" b...
FLASH IRQ handler not triggered on STM32H753.
Hy.I have a little problem. I developed an Ethernet based remote firmware update for the STM32H753 uC (rev. V) in a custom board.The processor erases the BANK2, and than programs it with the new firmware. When the programmed firmware checks correctly...
Resolved! Cannot get continuous data from SDADC
Background: I use the stm32373c evaluation board to make project. One part of the project is to use the 16bit SDADC to acquire sinewaveform generated from function generator and send the data to pc sw thr. uart. I follow the evaluation board example ...
Data not being transmitted via USART on STM32H7B3I-DK
What I am trying to do:Send and receive data via USART on my STM32H7B3I-DK. I am connecting a serial USB to the STMod+ CN10 RX and TX and have 2 serial consoles on for monitoring the data that is transmitted on both ends (the serial USB and the disco...
Resolved! Example for Dual CAN filter bank configuration (using two CAN)
Is there any example for using CAN1 and CAN2 in a dual CAN MCU like the STM32F777, especially how to configure the filter bank using the ST HAL (cube) ??As I understand the filter bank is shared. Are the FIFO0 and FIFO1 also shared?Why is there a CAN...
Interrupt Nesting on STM32H745ZIT6: How many nested interrupts?
If there are more than three interrupts triggered simultaneously in the interrupt service routine/callback, how many nested interrupt the board can handle simultaneously. Or there are some cases of memory stack overflow which can lead to the dumping/...
