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...
Hi.I have a program that sometimes fails to send data on CAN but still receives them correctly.This is on an STM32L462 using 1.4.2 IDE and latest API.For some unknown reasons, at one moment, out mailboxes never empty. It can be anytime from right upo...
I'm working in a project that involve a thermal camera image processing.I need to process a buffer of 384*288 (16bits) in fastest way possible.I'm using the 480Mhz VCO template to set the procesor in 400Mhz (Cache enabled).I already did some code op...
HelloWhen debugging, I obviously use ST-Link and Keil displays register values for meCan I export these values somehow without having to transmit them over UART?I need these values for later graphing in python and UART would just take unnecessary scr...
Hello,I am encountering an issue with the STM32F413 MCU: when transmitting data over UART, there is a short delay between the stop bit of one byte and the start bit of the next byte when transmitting data one byte at a time. I compared the behavior o...
HelloI was wondering about nubering in q15 fixed pointI am guessing that in 1.15, 1 (msb) is responsible for sign and 15 bits are for magnitude(I could be wrong)However what does 9.7 mean ? does it mean 9 bits are for whole numbers and 7 bits represe...
hello,i'm debugging this code suddenly i got a hard fault as shown in the figure:how can I solve this
In MX, at first, I changed the sample rate to 8 bits to double the baudrate. The code was successfully generated, compiled and downloaded. The communication still exists, but the baudrate is still the same as before, with a bit duration of 1.08us.The...
The STM32G4xx Reference Manual (RM0440) Rev 4, Figure 2, "Memory Map" on Page 81 says Option Bytes 1 is from 0x1fff7800 to 0x1fff7810 (16 option bytes), Option Bytes 2 is from 0x1ffff800 to 0x1ffff810 (16 option bytes).However:Table 7 on page 94 says...
What is the current consumption of STM32g071GB in deep sleep mode? I found the tables of current consumption in the datasheet, but I am not certain which is the deep sleep current among the list. I have seen the following:
I am working on a custom board with STM32F411RC which can communicate over SPI and I2C to the master board and acts as a slave in both cases. The master board also needs to be able to reprogram my board over I2C. Chip select signal is used to control...
