I am using Kicad BZR4022. After designing the PCB, while running the DRC I want to be able to detect the electrically unconnected tracks/vias in the board. How can I do this? I have searched online forums and have not found an answer. Also, if this option is not currently there in KiCad...
I have made a PCB with soldermask clearance as 0(Dimensions-> Pads Mask Clearance-> 0) , but the fabrication people has sent it back saying "We found soldermask expose on trace on both circuit layer" . Why does this happen? Ive attached snippets of my PCB where the Fab ppl points...
the delete button seems to be missing in the right menu bar after I installed KiCAD 2013(Build: 2013-07-07 BZR 4022) on windows 7. I was using KiCAD 2010 until now and it didn t have this problem. Since Delete button is very useful to me, I d like to know if someone else also has faced...
Got reply from STMicro forum.
"PB3 SWO is typically used in support of the SWV (Serial Wire Viewer), as far as I'm aware the Cortex-M0 does not support this functionality (Debug/Trace), or JTAG, so the pin can be left unconnected.
If may be connected in the schematic due to the way ST shares a...
I am designing a board using STM32F030F4P6. I have to use STM32F0 Discovery board STLINK for ISP. Checking the schematics of Discovery board, I found out that the ISP connector (SWD) is connected as follows:
6.PB3 of the STM32 controller on board...
I need to convert my .brd file in ubuntu KiCad EDA Build 20090216 final into a pdf document of the same dimentions. There are no options to export as pdf, so please tell me if this is possible.
I know it is not advisable to use delays, but using delays should not cause the problem that i stated.
if the controller is always in interrupt, it should at least execute what is written in ISR, I have written that it is not doing so.
PORTB is externally pulled down. Then why...
below is the code for external interrupt on RB0 of PIC16F877A controller. the issue is, external interrupt does not seem to be working with other peripherals. when the static void interrupt isr() routine is commented out, whatever is in the main program works. but as soon as the isr is...
How to generate a sine wave of frequency 50Hz +/- 10Hz controllable through a POT?
the amplitude can be +/- 5to12V, duty cycle 50%.
555 and 566 give only +ve wave forms, i need a wave with alternating polarity.
I am trying to build an energy monitoring application.
ADE7757 looks promising but i could not find a low cost solution using this chip.

I want my PIC16F877a to go to sleep and wake up when a query is received on UART via zigbee. the idea is remote data monitoring. I want the device to go to sleep and wakeup and send data only when queried. datasheet says this is not possible if i am using asynchronous receive interrupt. so...
energy monitoring using pic16f877a_which sensors to use?
I m trying to build an energy monitoring application. I have to measure power consumed in a domestic environment, and power generated in a solar panel. I am emulating the domestic environment with a load built with two 40W lamps...
