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...
Posted on January 29, 2012 at 16:18Hi, I just discovered, that unfortunately it is NOT possible, to use CAN2 together with USB-HS in the STM32F4 or STM32F2 device. CAN2-RX is available only on pins PB5 or PB12. But if Hi-Speed USB is used (ULPI inte...
Posted on January 26, 2012 at 10:28I need a delay in a timer 4 interrupt. To realize this I wrote the the follow lines:if(TIM_GetITStatus(TIM4, TIM_IT_CC1) == SET) { TIM_ClearITPendingBit(TIM4, TIM_IT_CC1); TIM_ClearFlag(TIM4, TIM_FLAG_CC3); while(T...
Posted on January 03, 2012 at 09:29Hi everybody, i work with the evalboard STM3220G with the USB example from the USB host-device lib. I try to write additional data in the create/existing file, but I'm not successful. Can anyone say me, what i must...
Posted on January 28, 2012 at 23:22In the STM32F4 I found some minor errors in the timer descriptions: - Page 395 - Description SMCR-TS for Timer 2...5: Should refer to Table 62, not 60 (Table 60 is referred at some points in the manual, but it does...
Posted on January 27, 2012 at 10:28Hi, in the reference manual RM0090 for STMF4, in chapter 7.1 it is recommended to activate the ''IO compensation cell'' (Register SYSCFG_CMPCR), if outputs are used with speed settings of 50 or 100 MHz (GPIOx_OSPEE...
Posted on January 27, 2012 at 11:54In Ref. Manual 6.4.11 Table 18, for the registers GPIOx_OTYPER a reset value of 0x4444 is specified, but I think this is an error - should be 0x0000? (as specified in 6.4.2 at the register description?).

Posted on December 15, 2011 at 05:18After transmitting a block of data, SD Card sends the CRC for the data.After sending CRC, SD Card sometimes puts itself in the ''Busy'' mode.According to the reference manual, STM32's SDIO peripheral's data path s...
Posted on January 27, 2012 at 10:02I use Stm32f103rb microprocessor on stm32p103 board. I want to control a thermal printer. Is there anyone who give me some example code for this situation ? Thank alot
Posted on January 27, 2012 at 12:23Hi, I have some questions about flash programming 1. how many writes to flash can i made beetwen FLASH->CR |= CR_PG_Set; and FLASH->CR &= CR_PG_Reset; is it possible to write here more data than 2 words ? (only 2...
