Hi, My brain is working hard on this topic, and I did little progress thanx to lectures you shared and ither posts of this forum. Here is my goal: continuous output 80 or 100MHz square clock from teensy pin 12 (IOMUXC_SW_MUX_CTL_PAD_GPIO_B0_01) on rising edge detect on teensy pin 2...

Thank you for your repply. If I can use FlexIO to do all the job (clock, triger and read input) it sounds good to me. But I didn't see any example on how to achieve this. Do you have references, documentation, codes to suggest ? Thank you.

Thank you for your repply. It sounds like for ma need FlexIO is the most suitable. Here is what I'd like to achieve: Using FlexIO to generate the square encode clock of my ADC, (80MHz, and 40MHz for testing), setting trigger of FlexIO on CLK+ rising edge, when a trigger occurs, generating...

Hello, Bonjour, I'm interfacting a LTC2207 16-Bit 105Msps ADC with teensy 4.0. I'm generating the (80MHz) square ENC signal from pin 12 using FlexIO, which seems to work well. Now I'm trying to read 8bits D0..D7 of ADC on the CLK+ rising front. I did a first try using interrupt on CLK+...

Hello, I have a Teensy 4.0, and I thought that the 3.3V pin was "regulated", in the sense that the 3.3V signal was accurate, which does not seems to be the case as I have 3.4/3.5V on the 3.3V pin, and it is actually a problem for me as I'm using this signal as comparison reference :rolleyes: Is...

Hello, I'm using DAC output to generate 170mV, but when I look the signal on scope I can see a lot of noise (see attached), do you have any idea of the origin of the noise ? I tried to connect my scope to GND and AGND, and with two different scope, the problem is the same. Here is my code ...

Hello, I'm using a teensy 3 together with a WIZ820io module, I use the Ethernet library for controlling the WIZ820io. When I use the WIZ820io alone, I'm able to send UDP packet without problem. My problem comes when I use a second SPI slave on my teensy (the first SPI slave is the WIZ820io)...

Hello, It seems that I solve my problem by initializing the SCK pin before Ethernet, not in the Ethernet library like this : SPI.setSCK(SCKpin); Ethernet.begin(mac,ip); Udp.begin(localPort); Sorry for the disturbance. Cheers. Julien.

Hello, I'm using a teensy 3.1 together with WIZ820io, I use Paul Stoffregen's Ethernet library for W5200. I'm able to send UDP packet from the teensy to my computer without problem, but the SCK pin used is 13, and I would like to use pin 14. I tried to modify w5100.cpp by adding SPI.setSCK(14)...
