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...
I found that the CubeMX 5.3 initlization code missing a part; specifically the HRTIM clock initialization where the PLL is defined. There's a related constant that also needs to be defined. In any case can someone confirm the problem and how long it ...
I have a project (STM32F407) that uses the Thumb Drive firmware update program based on the ST code * @version V1.0.0 * @date 28-October-2011Two questions:1)Is there a newer version we should upgrade to?2)What is the maximum thumb drive size? Small...
Does anyone have experience with getting the timer to run with input capture, I am unable to make the input capture function.I have a working system with STM32F03 (M0) devices initialization generated by CubeMX. Now I am testing an identical system w...
Hi,My code is generating a HardFault condition, is not every single time it pass the main loop, but after the first 5s it stops.The Hardfault not happen every time in the same line, that is what have been so difficult to track down, but it always sto...
