Posted on March 02, 2012 at 07:58GDay to all 1) what is the minimum frequency for calls to TSL_Action() to keep the TSL responsive? the spec only says ''periodically''. Is every 100 ms enough ? 2) what CPU-usage can we expect (at 32MHz) for the TSL ...
Posted on April 17, 2012 at 11:18If I try to configure the TS module on a STM32L151 all TS pin will appear green and blocked for other use. I like to configure only 4 pins for touch. This seems to be not possible with this tool or is there a trick?R...
Posted on April 16, 2012 at 13:18Hello, I just bought an STM32F4 discovery board. I installed the USB drivers (ST-LINK/V2 USB driver for Windows 7, Vista and XP) and the STM32 ST-LINK utility programmer. As a first step I would like to connect the ...
Posted on February 20, 2012 at 00:24The new STM32 MicroXplorer v2.0 is now ready for download, per an automated email that I received from ST. The web page says v1.1, but after downloading, the contents says v2.0 and I verified after I installed it...
Posted on April 25, 2012 at 09:01Hello,I have been doing some measurements with the STM3220G eval board using the piece of software at : ./STM32F2xx_StdPeriph_Lib_V1.0.0\Project\STM32F2xx_StdPeriph_Examples\ADC\ADC3_DMAThe ADC reading of the potenti...
Posted on April 22, 2012 at 00:24The EEPROM emulation demo uses Flash pages 2 and 3 (16 Kbyte pages). Flash pages 0 and 1 are also 16 Kbyte pages. WHat happens when your program is longer than 32 K? Is the linker smart enough to skip Flash pages 2...
Posted on April 24, 2012 at 15:57Recently migrate from 8bit MCU to 32bit STM32, I like the FW library, but there is a learning curve required. So I am trying to do a printf with USART, after i compiled the program, i cant receive anything. At this p...
Posted on March 06, 2012 at 13:40Hello, while studying the STM32F4xx datasheet i found the following passage:25.3.1: ''The NSS signal is driven low when the master starts the communication and is kept low until the SPI is disabled.'' This leads me ...
