STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
Hello, I' m working in team on a project using stm32 f100 series board. I should use an eeprom to storage and read some data, the eeprom is the following: CAT24C512WI-GT3 and I also have the init code for this I2C eeprom:void io_ee_scl(char s) { if(...
Hi,I just uploaded the MPU6050 library to communicate with my STM32F103.Example program is MPU6050DMP6.All works fine when I use I2C1 (default I2C bus).But I want to use the I2C2 bus (controller has 2). I found information stating: #include "Wire.h"e...
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...
