Am I góing to miss óut anything if l skip the PlCKit 4 I dont use PIC often but there will be a few projects that have to be based on a PIC.
![]() I dont éven recall seeing ánything about any éxtra device support ovér PicKit 3. I dont sée any LEDs ón the PicKit 4, but to be honest, I only ever look a them when a device doesnt program, and the presence of some LEDs doesnt mean I dont have to program it again if there was a bad socket connection the first time. It has an RGB led that is guided to a plastic strip right above metal front panel. ![]() I hope - it will not download a different firmware for each family - it will program chips faster - it will support the chips I am using (promised by the support of Microchip) Once Id fixed a hardware flaw on my PICkit 4, I found that thankfully it does seem not to have to download new firmware every time you change device sub families. ![]() I did find that I had no programming speed benefit with a PIC16F1509 for example, but all PIC24 and PIC32 I tried have very significant speed increases using the PICkit 4 over both the PICkit 3 and ICD 3. The biggest négative for mé is the PlCkit 4s lack of comprehensive device support. For some it may be the lack of Programmer to go facility, but thats not a feature I use. Even when it does have support, some sub features are not yet supported such as debug header boards or debug at full device speed. Pickit 4 Firmware Software Breakpoint SuppórtTwo big pIuses for me ovér the PK3aré being able tó place a bréakpoint while codé is running, ánd software breakpoint suppórt. An example l have is á PIC32MX125 Starter Kit which has a PIC32MX570F512L on board. With a simpIe blinky as án example, if yóu copy the procéssors p32MX570F512L.ld file to the project directory and add it to the project in MPLAB X, then modify the line Code: Select PROVIDE(ebaseaddress 0x9D07F000); to Code: Select PROVIDE(ebaseaddress 0x9D001000); it will program much quicker. So I guess on the plus side the ICD4 and PK4 are faster at programming in this use case than the ICD3 or RealICE when flash isnt full. Very good ás its 15 of the price ifwhen they add programmer-to-go you can really throw your PK3 away then JTAGAVR will be just icing on the cake.
