Hi, I am facing an problems that I have never seen before with local variables being allocated at the same addresses of global ones. In the attached image I show an example of a local variable with the address of another variable in the STEmwin libra...
Hi,I want to configure the FMC such, that it should just write 8 data bits in a VERY SIMPLE way - without any switching.I use the following code:#define RAM_D1_FMC_SRAM3(off) __attribute((at(0x68000000+off))) //global variables: int iDebugFMC; int ...
Hello, I'm looking to use Timer and DMA to drive a WS2812B LED with a STM32H7. TIM8 Ch2 is connected to the LED. I would like to explain what I understand so that its clear and I can get it working.A half word transfer from a memory location to the C...
https://github.com/STMicroelectronics/STM32CubeL4/tree/master/Projects/B-L475E-IOT01A/Applications/ProximityHi,I was going through the example of promixity sensor of B-L475E-IOT01A board in the github stm32l4cube repository. i compiled the code and d...
I have a photo interrupter attached to an interrupt port powered by the 3.3. volt supply.Every now and then, there is a burst of activity on the 3,3 volt line which cause havoc on the interrupt line.img_0933 shows the output of the photo interrupter ...
Hi thereI am trying to configure a GPS receiver chip (MAX2769C) with an stm32f446re MCU using SPI in half duplex master mode. The chip is expecting a 32 bit word (4 bits address and 28 bits data). This is on page 21 of the attached datasheet. My firs...
In order to wakeup the microcontroller from standby mode, is it necessary for the wakeup pin to generate a rising/falling edge or it should only have logic high/low level? In the datasheet it says rising/falling edge, however inside the HAL functions...
I'm currently receiving image data from TTL camera and sending it via Bluetooth. Baud rates for camera (VC0703) and Bluetooth module (HC-06) are 115200 and 230400, respectively. I'm defining camera rx buffer size and Bluetooth tx buffer size as 60000...
1) Index contains SYSCFG_MEMRMP but there's no such register in 'F3032) in 5 figures' caption, AUTODLY is mentioned, but there's no such bit, the correct name is AUTDLY (without "O", bit 14 of ADCx_CFGR).JW
Below is my benchmarking of multply-accumulate performance on contiguous memory blocks on the STM32F7508-DK board for three different types of memory (on-chip SRAM, external SDRAM managed by the FMC, and QSPI-connected NOR flash):The horizontal axes ...
