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 June 20, 2013 at 15:29Hi all, On my STM32F102R8T6 board, when the STM32 goes into standby mode, power consumption goes down to a few µA. But if I touch some pins of the STM32 with my finger or with a metal stick, power increases to severa...
Posted on June 20, 2013 at 15:05I recently extended the eeprom emulation code provided by ST to perform asynchronous page transfer when a flash page has no more space left. I need this feature because my embedded system runs in real time fashion (10...
Posted on June 20, 2013 at 14:18 I have found strange behavior of CPAL library when device is in slave mode. I use interrupt mode. When I'm waiting for read from master, I prepare data by: if ((I2C2_DevStructure.CPAL_State == CPAL_STA...

Posted on June 13, 2013 at 04:22Dear everyone,I'm using STM32F407 and I'm using quadrature encoder which is high resolution linear scale and maximum 2Mhz pulse speed.When the encoder speed is over 400khz, the data is missing.I would like to know the...
Posted on June 17, 2013 at 18:45What the diffrence between : ''TIM_CounterMode_Up'' and '' TIM_CounterMode_CenterAligned1'' or ''TIM_CounterMode_Down'' and '' TIM_CounterMode_CenterAligned2'' I cheked the datasheet and after reading I conclude that ...
Posted on June 20, 2013 at 05:05Hi All, trying to learn more about the system control block and it's control of the stack pointer. Using the STM32F03. I have searched RM0008, and DDI0337E_cortex_m3_r1p1_trm.pdf discusses it's use, but not specifics...
Posted on June 18, 2013 at 20:47This is a really basic question, but I'm just starting out on this board. I've been able to run programs through the Debug interface of ST-Link in Eclipse. Now I'm trying to get printf working with USART2, so I need ...
Posted on June 19, 2013 at 19:29Hi all, is there a way how to definitely disable JTAG ? so it will be not usable anymore ? i'm scared of flash code steal (of course when Read-out protection enabled) ... Kind regards,
Posted on June 19, 2013 at 08:02I have an STM32F4 project that uses DMA for UART transmission, and it's working well. I now need to add the ability to interrupt the DMA process and send a single byte immediately (or, more specifically, once the byte...
