### ICSP or Pre-Programmed Microcontroller

If you have the space for a header, that's probably the best option, and the slightly staggered pins Majenko recommends is a good way to hold a connector in place without adding complexity. But here'...

### ICSP or Pre-Programmed Microcontroller

I would suggest always including a header in that kind of quantity (small). If you get to larger quantities you can consider pads for pogo pins (you'd have to make a fixture to hold the PCB in ...

### How to Use an External ST-Link/V2 with the STM32F4 Discovery Board

You'll need to isolate the microcontroller from the st-link portion of the board. To do this just remove the jumpers on the CN3 pins. Then, to use your external st-link, make the following ...

### ICSP or Pre-Programmed Microcontroller

I always add space for an ICSP header, even if it's not populated. I have three ways of doing it at the moment depending on situation. One of my designs has a very fine pitch header for which I have ...

### What's the risk of leaving VPP/MCLR floating?

It's not 'floating' in the second circuit, that particular PIC has an internal pull-up. You should read the datasheet for the particular processor you are using. It's only 404 pages, a trifle ...

### Can a Raspberry PI be used for high voltage parallel programming?

No. It says that you can use an Arduino for HVPP with additional hardware. Similar hardware (a shield or hat or pants or whatever Raspberry Pi calls it) could be developed for the Raspberry Pi, but ...

### avrdude: error: program enable: target doesn't answer. 1

I was pulling my hair out as I had received 20 Atmega328P's and the first one I was able to get programmed with my USBasp Programmer, but swapping the processors I was not able to program on ...

### What is needed for basic PIC programming?

I would say that you lose your PICs in the basement. They are "C" devices and do not have Flash. This means that they may be erasable by UV (Quartz Window) or totally non-erasable OTP devices. You ...

### Why do I have to disconnect and reconnect the Microchip ICD3 after every programming?

I haven't really solved the problem, but I've found a rather ugly workaround that is just barely better than nothing. I've written the following python-script to reset the USB-port. This gets the ICD ...

### PIC18F1220 production build of C code not working

Problem here is that the PIC18F1220 and 18F1320 require that the MCLR pin to be connected at least to Vdd through 1-10kOhm resistor. This enables the POR as the datasheet states. If the MCLR pin is ...

### Absolute cheapest, (easy) way of starting programming on ARM microcontrollers

The easiest start probably is one of the third-party clone boards. Random example from ST. That requires a programmer using the 'SWD' protocol. ST make 'ST-LINK' branded ones, I'm not sure if you have ...

### Can I covert a 3.3v/5v USB TTL Serial device to 1.8v using a LM1117 1.8v regulator?

Pin 4 of the PL2303 or FT232R SOIC package is VDD_325/VCCIO, the Serial level voltage input. If you inject 1.8V there, the serial UART pins will be at 1.8V TTL levels. http://www.prolific.com.tw/...

### ST-LINK/V2 repairing issue

You need to upload ST Link firmware onto the MCU. It might be possible with some soldering/desoldering involved. I am not sure if the original firmware is available freely, but there is STSW-LINK007 ...

### How can I tell that USBasp is working?

The error message you are seeing means that the chip is not responding to the "enable programming mode" command that the programmer is sending. Either you have got the connections wrong, or the ...

### What is the difference between Microchip and ICD and PICKit?

The main differences between ICD4 and PICKit 4 are as follows: o Power to Target: ICD4 can provide up to 1A, whereas the PICkit4 can only provide 50 mA. o Breakpoints: ICD 4 supports complex ...

### Will one pic programmer program all pic chips?

Unfortunately, there is no single programmer that will program all PICs. If you go to the in the installation directory for MPLABX (on my machine it is "C:\Program Files (x86)\Microchip\MPLABX\docs"),...

### Programmer gives me an error in programming a big hex file

All these Programmers are based on USBASP which is not professional programmer/debugger tools and many parameters e.g. USB cable length make some problems at writing speed and performance. I had same ...

### Program a PIC24FJ64GB002 with a pickit 2

PICkit 2 does not support the PIC24FJ64GB002, either as a programmer or as a debugger. See below from MPLAB
