My circuit board USES PE6 to control the backlight, but it cannot be adjusted. How to modify the device tree of TIM15_CH2.EV1 is not regulated.EV1:panel_backlight: panel-backlight { compatible = "gpio-backlight"; gpios = <&gpiod 13 GPIO_ACTIVE_LOW>...
Hi allI would like to know if STM32L072 can use interrupt for USART4 & 5.I'm using 1,2,4,5 serial ports .If not, is using STM32L151 would change something or not ?Thanks for help
Hello, we are building a project on an STM32F7, and so far it's great. Our device includes an SDcard, and we are using the HAL layer code. There is a function HAL_SD_WriteBlocks_IT which has worked fine, but I take a closer look and I see that it sen...
Hello,I am using a STM32H745 in LQFP144 package and as far as I understand it supports only muxed PSRAM since the pins for non-muxed memory are missing in this package and the CubeMX software does not have the option to setup non-muxed PSRAM on this...
STM32 standby mode, standby wake-up pin PA0 and RTC wake up, both can work normally. The problem encountered is: If the wake-up pin PA0 is kept high, when the PA0 high-level hold time exceeds the wake-up time set by the RTC after standby, the chip di...
In datasheet is 6.3.22 Operational amplifier characteristicsILOAD Drive current max 500uA.Does this mean the amplifier cannot control the negative current?RLOAD Resistive load min 4kOhn? Why 4kjOhgm, for exmple curtent to 4kOhm for 2.5V is 625uA, thi...
hi sir, I want to use timer channels to OC mode. In that same timer interval i need set time to channel 1 come 1 time and channel 2 comes 5 times.example: In 1 milli second timer i need set & reset channel 1 for time and every 200 micro second set ...
I am trying to read data from from BMP 280 bosch sensor but could not able to do , Any expertise on I2C/ Bosch sensor please?I could able to communicate with my sensor by checking if the device address is right or wrong using function : HAL_I2C_IsDev...
I am trying to run a boundary scan test on a custom board with a STM32L4R5ZIT6, My boundary scan tool of choice has highlighted some inconsistencies with the pins. When I set certain pins the wrong pins get set.I checked the resources section on you...
