Hello!i develop an outdoor temperature measurement system and read every 30 minutes the ADC values -> all works fine! ADC calibration was done one times after start up.Now i changed the ADC calibration and calibrate every 30 minutes just before i rea...
Hi all,I'm hoping you're able to help me with a problem I'm having when trying to enable CAN on the STM32F105.OverviewBit of an overview first for context. The idea behind the project is to enable both CAN buses on the MCU so that they're able to tra...
I am using STMCUBEIDE there i was using optimization level as "optimize for debug". there i used a local variable as uint8_t and i am incrementing its counts then memory exceeded to 85%. if i removed increment then only 37% flash memory occupied.
Dear community,I am planning on using the STM32L476RG for a project. That project is a low power application, so the current consumption is really important to this project. However I cannot find any reliable source for the current consumption of the...
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 ...
Hi,I am using the internal EEPROM of the STM32L151CBT, with SYSCLK 32Mhz.Access to the EEPROM is done using the HAL functions present in stm32l1xx_hal_flash_ramfunc.cHAL functions are defined as __RAM_FUNC and placed in the ram segment:__RAM_FUNC HAL...
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...
