Please ignore this for the moment. Looking at EventResponder.h I saw EventResponder::attachInterrupt and that appears to be working fabulously but I'll report back if I am still having problems. Sorry for the noise. BBUK

Hi all I have an application where I need to undertake a short SPI read every 60us or so. I am interfacing a T4 with an ADS131M differential ADC. The ADS131M has a dataready signal that asserts (strangely enough) when data is ready to be read and I was thinking of using attachInterrupt to...

Thanks manitou. Oops. I provided a simplified sample of my code without checking it. Your code works fine. This, however, demonstrates what I am experiencing (properly tested this time): #include <SPI.h> void setup() { pinMode(0, INPUT_PULLUP); pinMode(1, INPUT_PULLUP); SPI1.begin()...

Hi all. When I initialise the Serial device (i.e. USB serial), it seems to unexpectedly initialise the pins for UART1 as well. I have an application where I am using digital pins 0 and 1 as ordinary switch inputs. Closing the switch pulls the pin to ground. I naturally need pullups. Using...

Hi all. Just to confirm that T4 SPI is now working much better for me with the changes to the SPI pin drive strength in this beta. I am using a 1.8V SPI device through level translator and was experiencing some problems. Thanks
