Hello all, I have started a rather ambitious project. I want to create a good smart watch. I have stm32l4r9 discovery board. My idea is to test how discovery board integrated Cortex M4 MCU can be integrated with separate BLE module, which comes with ...
i am trying to bit bang 14 bits grey code. my output is not steadyuint16_t readbits(uint16_t dataPin, uint16_t clockPin) { uint16_t value =0; for (int i = 0; i <14; ++i) { value <<= 1; HAL_GPIO_WritePin(GPIOC, clockPin, GPIO_PIN_RESET); delay_...
I try to interface Cypress 4343W Wi-Fi module with STM32H747. i managed to port WICED SDK in STM32Cube IDE but when i start to send data using CMD53 i have problems that the DPSM always active which means from my understanding that the transmission s...
When the USART is hot swapping，some datas will occur on TX RX pin；and the value of BRR register will be changed;the picture 1 shows the BRR before hot swapping;and the picture 2 shows the BRR after hot swapping. Why this question happens?And what...
Hi,According to datasheet, The main function of PA15 is JTDI, so I disabled JTAG and config that pin in AF_PP mode.Then if I don't initialize SPI1, I can control PA15 as GPIO. But if I initialize SPI1, this pin will hold high. Since SPI1 has occupied...
In trying to understand some motor control code in the ST Library I've come across some procedure names with STO_ as a prefix. Simple question what does the acronym STO mean?
Hello. So like title says I am having trouble making SDMMC work with DMA in 4 bit mode. I tried with FreeRTOS and without FreeRTOS didnt get anyresult. But it works perfectly without DMAIt gives either Rx Overrun error or timeout error. I tried it wi...
We are intending to design in this MCU. Does ST have a website that would indicate where this part is in its lifespan? I can only see that it is listed as "active".Thanks
Hi there.I have a board from some equipament which has a STM32F091CCT6 uC, and there are 3 leds, connected to pin GPIO_C13, GPIO_C14 and GPIO_A7. Anode from leds are connected to Vcc and Catode are connected in a resistor and then to the uC pins (so ...
Hello all i am trying to implement a simple thing that is trying to blink LED using a function. Below attached are main.c, project.c and project.h. If i try the same thing without using a function it works fine but if i use the function it doesnot bl...
