Switching to Windows IOT from Linux

Hi, Does anyone knows if Windows IoT simplifies interfacing SPI slave devices ? Here is good article about SPI https://ms-iot.github.io/content/en-US/win10/samples/SPIAccelerometer.htm My question is how easy is to: 1. Add external interrupt handlers for interrupt coming from ADXL345 device ? 2. Use...

Re: SPI driver latency and a possible solution

Is there any example for using the new driver ? Especially for the following use cases: [*] any GPIO can get used as ChipSelect - we are no longer limited to 2 SPI Devices on the bus! The driver includes copying a 64Bit timestamp (based on a 1MHz clock) of when the SPI transfer terminates (and it wo...

Raspberry pi won't boot, only red power light active

Hi, On raspberry pi model B everything works fine for 2 weeks, then on next boot it enters a state where only PWR led is lit and system won't boot. I found on this forum that causes can be bad power supply and sd-card corruption. When I plug sdcard in new board everything works. This rules out sd-ca...

Re: CSI low level control

You should wait for Broadcom to add the CSI hardware to the peripheral specifications. Gordon (Raspberry Pi - Director of Engineering) is communication with Broadcom on this subject.

Re: Camera Interface Specs

Interesting that I haven't heard about this conversation since if anyone is the right person to ask its me! Anyway concerning HDMI -> CSI So there is the possibility of doing this, but it'll have to take a back seat behind and number of other projects. Of course it would be a very useful project fo...
