Hi, I would like to use the MDMA with the QSPI on an STM32H743 or similar.I need to use the QSPI to interface with several multiplexed LCD displays and I want to use the QSPI in 'indirect' mode to send commands to the displays and DMA the pixel data ...
Good morning, I have been trying to make simple characters appear on the 16x2 character LCD display for a while now and I am using a U575ZI-Q core board. I have followed many tutorials but none of them have allowed me to display a simple line of text...
HelloI use CAN FD and have a functioning communication with 3 participants. Now I want to activate the interrupt that notifies me when the device has lost the arbitration contest. I forward each of the four NVIC interrupts in stm32h7xx_hal_fdcan: voi...
Posted on March 24, 2017 at 11:03Hello there,Currently I'm using a STM32F407VG discovery board to testing the stm32 low power features. STM32CubeMX was used to generate a simple demo. However, it seems always not able to enter sleep mode (standby mo...
I'm on STM32F103CBT6.I have a TI DAC8564 on SPI2. It has a 24-bit input register, requiring me to TX a pair of 16-bit values (extra 8 low bits are ignored) while SYNC is low. After sending, I have to toggle SYNC high and then low to begin a new wri...
I don’t understand the behavior of the _C ports. According to the datasheet, the pin type for PA0_C is listed as ANA (analog input only). However, I can configure it as an output and successfully generate a square wave by toggling it in a loop.Given ...
Hello,STM32F103RB microcontroller.I want to use Using one timer as prescaler for another timer mode (see figures below).I want the slave timer to increment its counter every time the master timer generates update events. But the slave timer does this...
Hi! I have custom board with new mcu stm32l562ve. Board has out pins - SWDIO and SWCLK.I am try connect by st-link v3. But mcu not connected. Also, i tested with connect nRST ( setting "Under Reset" in st-link ). But this variant same as first. MCVU ...
Hi I am wanting to use the LPTIM to break out of STOP2. I have a function to set the timer, and go into stop mode. After setting LPTIM1->ARR, LPTIM_ISR_ARROK in the LPTIM1->ISR is never set. After X amount of seconds, the STOP2 exits as expected,...
Hi, I have a custom board in which VREF+ is supposed to be 3.3V. But the actual VREF+ (pin32) is 2.xV, with drifts between power ups. VDDA (pin 33) is 3.3V.What's wrong with the circuit schematic? Can I just remove the resistor (R22) between VREF+ an...
