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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello!I am trying to read data by QSPI (MCU STM32F722VC). But QSPI always reads out the last value written to DR register by previous operation and does not read data from data lines. For exapmle, DR value is 0xAA from previous write operation. Then ...
In STM32CubeG4 Firmware Package, the G474 digiatal power demo use a FMAC to contol a buck or boost toplogy with one voltage control loop.So if I want to use two loops,one for voltage and other for current loop, could the FMAC(in my opinion,that is j...
Actually i got the project on modbus but i am trying to code without using libraries but i am not getting expected result. can anyone help me with this and what extra line i need to add in my code please.Thank you
I am using i2c ,arduino as master and stm32l073RZ as slave.When I transmit from arduino(master) to slave(st) via i2c.I am getting correct values.But when I slave transmit from st the first byte received in arduino-master is ffffffff,the other bytes a...
Hello,I'm some confused how external interrupt is working with GPIO. If PA3 and PB3 are both configured as external interrupt, and assume the two interrupts are not coming simultaneously, how to determine which PIN generates the interrupt when EXTI3 ...
I've been using the following two bit timings for a CAN bus speed of 500K on the STM32F103. I was just wondering which is better? Does it make any difference? Is there another preferred option? Thanks a lot for any insight. //(1+9+8)*4 = 72 //1+9+...
the target type is stm32f072, firstly the master transmit data success, slave receive data ok; should i need to disable spi ,enable BIDIOE in slave. but the slave can't transmit data, how to solve it?
Hello Everybody,I am using the STM32H743ZI chip with STM32CubeIde. I have been having success with my code running in debug mode with the debugger attached. however when I power off the board and start it up there is a problem when the program start ...
Hello,my question implies that there is no value for TS_CAL2 available for the STM32G070, although its reference manual RM0454 describes it on page 292 (14.9 Temperature sensor and internal reference voltage: Reading the temperature). Since there is ...
Dear all,I need geneate an interruption about 5Mhz to access to an external device using FMC. I am trying to use a Timer to generate that interrupt but I do not get the results I expect. On STM32F429 and STM32CubeIDE, I config timer 10 with the foll...
