Hi,I have a NUCLEO L552 and I would like to run a very simple program (just blinking a led).I have placed my vector table @ 0x08040000 as described by the data sheet. to program the flash I use the J-Link from Segger. What is strange, is that I canno...
Hello,I'd like to use my STM32F446 in the following way:ADC 1&2 are connected to an analog sensorOnce the sensor connected to ADC 1 passes a certain voltage, start using DMA to transfer ADC 1&2 values to buffers.Once the transfer is complete, stop th...
Hi everybody ,does anyone have source code for writing data in SD card?I am using STM32F103C8Txthanks alot
HAL_RCC_GetSysClockFreq(void) in stm32f7xx_hal_rcc.c uses a (unt64_t) divide which could be avoided. This uses, on my build, 716 bytes of code space alone for the required _udivmoddi4 call, and this is not used anywhere else in my code.Would it be po...
I'm trying to send exactly 8 bits of data, and check my results with tera terminal, however I'm not seeing anything come up. I noticed that on the block diagram for the STM32L476RG nucleo board, that the APB1 Bus is also connected to AHB1, but there ...
Hell guys, i'm trying to communicate with LCD2004a with the I2C extender.i followed this guide https://www.youtube.com/watch?v=7mQppaEJjT4what i did:I generated project using CUBEMX to Keil uvisionconfigure I2C with those parameters: 100Khz CLK, slav...
I am working with a STM32G474 and I want to use a PWM with 390kHz for a boost converter. I generate a PWM with the HRTIM WaveformOutputStart. Using WaveformOutputStop pulls the LPWM to low, but the HPWM remains on high.
Hi everybody! I've been struggling with this monster for a few days now. I'm trying to make it do some very basic (pun not intended) things and I have little hair left... But let's cut a (too) long story short: I'd like to send with the SPI a few byt...
Suppose that my system consists of 3 modulesmain... at the end of the while loop, I want the system to enter sleep mode, so at the end of the while, I put wfi(); or possibly I put DSB(); after that. Other examples replace wfi() with HAL_PWR_EnterSLEE...
I am using a keyboard to read several commands using HAL_UART_Recieve(). For each command I perform a different function. There are 3 such commands corresponding to one function each.Assuming 3 functions multiply(), divide(), add() which are called i...
