Equipment for our Simple Microcontroller tutorials (PIC10F200) - Part 2New
Hey there! If you are reading this, then the introduction caught your interest and my efforts were not in vain. Excellent!
While the microcontroller is the brains of a project, there are a lot of other things required for a functional circuit. So, let’s first figure out what we will need to develop our devices using the PIC10F200 microcontroller.
1. PIC10F200 Microcontroller
The PIC10F200 microcontroller itself - obviously. You can buy it in whichever package you want and wherever you want. Personally I bought the microcontrollers in the DIP package for easy prototyping and so I can use a breadboard (yeah, I’m spoiled by the Arduino too). I purchased the PIC10F200 on Aliexpress, which I use quite often to buy electronic stuff when it’s not quality-critical. Again, if quality and reliability are critical, go to an authorized distributor.
2. Programming Tools
A programming tool. I don’t want to limit you with this. You can use any one you want – from Microchip or DIY. The only thing that is mandatory is high-voltage programming support, as this is the only programming option supported by PIC10F200. From the original OEM programmers/debuggers you have the following options:
- PICKit2 - obsolete now but supports the PIC10F family and can be used.
- PICKit3 - also about to be obsolete but currently the most popular model.
- PICKit4 - the latest version of the PICKit, it supports the whole set of Microchip microcontrollers including Atmel AVR and ARM chips, so if you need an all-in-one tool, I’d recommend this.
- MPLAB ICD2 - an in-circuit debugger, more advanced than the PICKit, this version is obsolete.
- MPLAB ICD3 - a newer version of ICD but not the newest.
- MPLAB ICD4 - the newest version of the ICD, supports PIC and ARM chips.
PICKits are much cheaper than ICDs. For instance, a PICKit4 costs ~$50 while an ICD4 costs ~$250. But it’s up to you what to use, I always recommend cheaper if possible because you can buy a lot of cool things for your circuits for $200 and if you’re not using it professionally, the PICKits are going to be just fine.
Another option is to buy or assemble clones of these programmers/debuggers - they are even cheaper but producers can’t guarantee that they will function properly. For instance PICKit2 can be found on Aliexpress for about $8-$9, while PICKit3 costs $9-$11. So you can use them but at your own risk – if something goes wrong, it’s your responsibility. As for me, I use a PICKit3 programmer, and I’m satisfied with it but in the office, we also have PICKit 2’s and a PICKit 4.
3. Other Parts, Breadboard, and Dupont Wires
In addition to the microcontroller, you will need some other parts and boards. Before each project, I’ll give a list of required parts but here’s an overall list for at least the first few hands-on projects I’ll do with you:
- 1 kOhm resistors
- 10 kOhm resistors
- LEDs (any color you want)
- Tactile switches
- Passive piezo buzzer
- Dupont wires male-to-male (these are great but just regular jumper will work if needed)
- Dupont wires male-to-female
Perhaps it’s obvious, but I need to mention that you need a computer of some sort. It’s preferable if it’s pre-installed with Windows 7 or higher but macOS or Linux will work as well. Just a warning, I’ll use Windows 7 in my examples.
Apart from the hardware tools and parts, we need some special software to write and compile our programs in Assembly language. You also have a choice here:
- MPLAB IDE v.8.76 is obsolete but it still supports the PIC10F family, and can be used. This IDE is only available in Windows.
- MPLAB X IDE is the current IDE version; it supports all Microchip MCUs, can be installed on any OS, and has a lot of features and plugins.
It’s up to you what to choose. MPLAB 8.76 is very lite, it requires less than 120 MB, and is not very demanding to the processor. MPLAB X requires more than 4 GB and can be laggy on an older or weak computer but the latest versions of PICKit and ICD are supported on MPLAB X. And, if you use any OS other than Windows, the only alternative for you is MPLAB X.
Both MPLAB 8.76 and MPLAB X include free usage of MPASM, a compiler that turns the assembly we’re going to use into machine code, keeping costs down.
Personally, I prefer minimalism, so I’ll use MPLAB 8.76, but I’ll show some critical differences to make sure you can find essential features in both IDE’s.
And that’s it for this tutorial! Before moving on to the next tutorial, as homework, you should purchase all the required tools and install all the required software. But there’s no hurry – in the next two articles I’ll tell you more about the PIC10F200 microcontroller and Assembly language. I know theory can be boring but it’s a necessary evil, without it you won’t understand the next tutorials. And, the seemingly boring theory translates into exciting projects!
