I'm trying to understand how SPI works on STM32. I use a STM32L472-discovery kit which includes a L3GD20 gyroscope sensor. On the board, STM32L4 is connected to the sensor via SPI2. I configured the GPIO pins needed for SPI2 and provided clocks to th...
I want to charge the Android phone along with USB data transfer. I am using STM32F072C8T6 as micro-controller and NCP1855 for mobile charging.The problem is this, in some mobile phones the charging is happening but the USB is not getting detected(And...
I have absolutely no problem with working with the registers, but we now have inconsistent use of low layer drivers and accessing the registers directly in my team's code base.
HiI am able to erase two pages (my array is length 256 ), now I want to write my array to a particular memory location.Here set is the address which is 0x080E0000p_source is my uint16_t array which I want to write to flash. And length is 256.How do I...
Hello,According to the Reference Manual of the STM32L431 controller, the ADSTP in the ADC_CR register must be set to 1 to stop the ADC. Additional condition is that both ADSTART=1 and ADDIS=0 must be. Once the ADC is stopped, the ADSTP bit is cleared...
The device in question is a STM32F030F4P6. I want to know if there is any risk of programming a device before sending it through a reflow oven (lead free soldering temperatures). We do this on other devices without issue, but I'm not certain if this ...
If I want to do some communication using SPI or UART, there are options like DMA or Interrupt, both of which give me callback. That means after MCU issues or start Tx/Rx function, it is free to do something else while waiting for the Tx/Rx complete c...
hello , I use spi and ı use slave mod spi. When I send a frequency of 500khz or more as a clock so data is shifting or I recieve wrong data but I send a frequency less than 500 khz I recieve true data. what is the reason of this.( use stm32h743z...
This is the how I'm trying to write to flashBasically I pass my uint16_t array to a function called FLASH_WriteA which accepts the array, the destination array or the location and the lengthvoid FLASH_WriteA(uint16_t * src, uint16_t * dest, uint16_t ...
In FLASH_OPTR, both DBANK and DB1M are r/w and have no restrictions beside that PCROPA/B needs to be disabled. For 1M device there are two(?) sensible settings DBANK=1, DB1M = 1 for 1Myte dual bank continous modeDBANK=0, DB1M = 0 for 1Myte single ban...
