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...
Posted on August 01, 2011 at 10:17Please could someone post the details to manage the SPI NSS signal? I want to use the SPI as a full-duplex master (sending and receiving data simultaneously). I have read many posts about the NSS deficiencies in the...
Posted on August 17, 2011 at 11:40Dear collegue,I have lunched the example project about I2C simple communication with interrupt that we can find in the UM0427 (user manual about firmware lib v2.0.3).The simple application is based on the main showe...
Posted on August 08, 2011 at 10:13hi. i would like to start anew project with stm32f207 with lcd. i know that the stm32f207 can controll lcd throw FSMC bus my question is whats the maximum size of lcd i can use and how do find whitch LCD monitors i...
Posted on August 17, 2011 at 00:55Are there any code examples or documentation of different types of PSRAM which have been used on the flexible static memory controller of this family? #stm32f-2-fsmc-psram
Posted on August 10, 2011 at 22:29hey everyone,it is first time for me programming any kind of processor and trust me i am trying very hard to figure out..i am using STM32VL discovery board in my project work.i have 3 sensors which will give me ADC ...
Posted on August 12, 2011 at 19:06Hello.I have a problem with starting OTG FS in Device mode. I will try to adapt project example ''STM32_USB-FS-Device_Lib_V3.3.0'' for this STM32F-2 chip, but USB doesn't run. For new chip I'll do next: 1. Prepare s...
Posted on August 15, 2011 at 05:52Hi,I am doing a very simple test, enable EXT11 interrupt. In the ISR, I toggle a GPIO pin. I connect the scope to both EXT11 line and the GPIO I am toggling in the ISR.They somehow do not match. It seems ISR is skip...
Posted on August 12, 2011 at 15:05I have no clock on PC12. But when PC12 is OUT mode it is work. If I run mySDInit() I will see two jump on pc12 ( out mode test ). No clock. Where is the bug?void mySDInit( void ){ uint32_t regSDIO_CLKCR; GPIO_In...
Posted on August 15, 2011 at 13:50Hello I would like to switch from the HSE oscilator to the HSI oscilator if there is a failure of the HSE oscilator. How can I do that with preserved SYSCLK (64MHz)? The HSI klock is divided på 2 så the PLL would ...
Posted on August 09, 2011 at 08:41Hello, Since the beginning of the project on the STM32F205RG, I had hard faults from time to time. These last days, I wrote a hard fault handler as described in Joseph Yiu's book to see why ... and the result was ve...
