#149574 - Depends on your application Responding to: ???'s previous message |
Hello Ricardo,
I all depends on your end application, or what you intend to focus on, or what product you are interested to make. You will have to choose the controller (or controller family) to suit the application, keeping in mind various factors such as price availability etc. First question: I have an Intel's P80C52 PIC, from 1980. In here: http://www.8052.com/faqs.phtml?FAQ=119883 I can read it has maskROM, and wikipedia: http://en.wikipedia.org/wiki/Mask_ROM says i cannot reprogram it, can you confirm this? The 8052 (or 8051) known as the MCS51 family has a huge derivative base, modern controllers come with built in flash so that you can program them again and again (within manufacturers specified limits off course), you can start your quest with the P89V51RD2, this has plenty of flash for you to experiment, cheap, can be programmed through your serial ports using FlashMagic, besides you may get a lot of help from this forum. I am asking this question to be sure i am going the right way. Since im about to learn to program a PIC, what should i choose: a 8051-based PIC or a 8-Bit Risc based PIC? In my opinion you are better off with the 8052 series than with a Microchip PIC series. Or even better, should i choose another PIC like an ARM7? Probably it would be even better for you to dump both the above families and jump into the ARM bandwagon, I think the ARM family is going to be THE microcontroller of the near future, instead of wasting your time learning old technologies from the 1980's. I have no experience with ARM, but I have recently purchased the ARM microcontroller from NXP, the LPC2364, these have huge amounts of flash and a lot of modern peripherals. The LPC23xx and the LPC24xx seem to becoming very popular around the world. Regards, John. |
