  1. Hello guys, I am using Zybo Z7-10 and want to use a timer which polls e.g. every 100ms by starting a task in freertos. What is the best way to implement such timer? Do I need to use XScu_Timer or Global Timer or Watchdog Timer Thanks, Mirco
  2. Hello all. I have some misunderstanding with TTCs on zynq-7000. I used this guide to understand how TTCs are working, but seems like a quite subtlety which I don't understand. I have to use 2 TTCs with PWM (match value) and change RC in handlers to make CNC. After trying to make it like get new RC in handler and change RC I got unstable error for about 0.5s for 25s of changing RC and some impulses haven't generated but handler was called instantly after changing RC (I took into account that (RC - match value) should be greater then 0). I thought it can be because I have to: 1)
  3. I'm using Arduino 1.6.9 with ChipKIT core and a DP32 rev B. My code sets up an interrupt for timer 3. When I set the prescaler to 1:32 or less, the interrupt runs just fine (although with some quirky behavior that I'll explain below). However, when I set the prescaler to 1:64 or 1:256, the interrupt appears to fail. My code is included below but I'll provide a brief explanation of its function here. The ISR increments a count variable, and sets a flag variable to high. The loop checks to see if the flag is high. If it is, it toggles LEDs 1, 2 and 3 to represent bits 5, 6, and 7 (resp
  4. Hello Guys! I hope you can help me with some doubts. I have a code that I use the ADC, TIMER and ETHERNET modules, when I try to compile it some erros are reported, as follows: C:/Users/MyName/Desktop/mpide-0023-windows-20140821/hardware/pic32/compiler/pic32-tools/bin/../lib/gcc/pic32mx/4.5.2/../../../../pic32mx/bin/ld.exe: small-data section exceeds 64KB; lower small-data size limit (see option -G) chipKITEthernet\utility\DNS.c.o: In function `DNSEndUsage': C:/Users/MyName/Documents/mpide/libraries/chipKITEthernet/utility/DNS.c:208:(.text.DNSEndUsage+0x0): relocation truncated to fit: R_MIP
