Dean Camera e322f14620 More fixes to the AVRISP command timeout system so that it should no longer lock up while processing command no matter what the conditions.
15 years ago
Dean Camera ce8d0424b1 AVRISP programmer project now has a more robust timeout system, allowing for a doubling of the software USART speed for PDI and TPI programming.
15 years ago
Dean Camera 331e8dece6 Use _delay_us() function in the XPROGTarget.c file to ensure timing requirements are met, rather than a fixed number of NOPs.

16 years ago
Dean Camera b1dbd92c32 Fixed AVRISP PDI race condition where the guard time between direction changes could be interpreted as a start bit. Fixed TPI interface lines not being changed correctly when in bit-banged TPI mode.
16 years ago
Dean Camera e1c1c25619 Change the AVRISP project's RESET LINE makefile tokens to AUX LINE, as it is not always used for target reset.

16 years ago
Dean Camera 022035839e Remove missed timer 0 init code in the ISP protocol handler in the AVRISP project. Switch the XPROG protocol target communications handler over to using Timer 1 COMA/COMB ISRs for the two physical layers, rather than COMA/ICR1. Speed up bit-banged USART mode slightly.
16 years ago
Dean Camera d1608d4af3 Added const where possible to the source functions in the Projects directory.
16 years ago
Dean Camera 65fcebf478 Complete combining of PDI and TPI target communication code files, stub out TINY NVM controller functions.
16 years ago
Dean Camera cfdab42dcf Rename PDITarget.c/.h to XPROGTarget.c/.h so that both PDI and TPI programming can be included in the one set of files.
16 years ago
Dean Camera 9decc2bc59 Combine PDIProtocol and TPIProtocol into a single XPROGProtocol set of files.
16 years ago
Dean Camera ce044844ea Combine AVRISP project TPI and PDI lib directories - these protocols use the same underlying XPROG wrapper for the host-to-programmer command wrapping.
16 years ago
Dean Camera 31d7194252 Make seperate ISP, PDI and TPI folders in the AVRISP project Lib subdirectory to hold each protocol's files.
16 years ago
Dean Camera cda88cf97c Start of implementation of the low level TPI programming protocol in the AVRISP project.
16 years ago
Dean Camera 37c9ba7fa9 Fixed AVRISP project timeouts not checking for the correct timeout period (thanks to Carl Ott).
16 years ago
Dean Camera b408a5fe62 Add const qualifier to the parameters of Projects' functions where possible.
16 years ago
Dean Camera 021b1b567e More speed and quality improvements to the software USART in the AVRISP project.
16 years ago
Dean Camera f0b4d79629 Slightly speed up software USART in the AVRISP project - faster parity computation, ensure received data is byte aligned when receive is complete by throwing away the start bit during reception.
16 years ago
Dean Camera 461607020c Use default NVM base address in the AVRISP programmer project in case the host programmer software doesn't set it correctly.
16 years ago
Dean Camera 4f74075fad Speed up bit-banged USART code in the AVRISP project.
16 years ago
Dean Camera a7880ac1cd Fix error in AVRISP programmer when repeatedly using PDI mode via the hardware USART due to the SendByte routine not clearing the Transmit Complete USART flag.
16 years ago
Dean Camera bb38793312 Add Doxygen documentation to the completed portions of the PDI programming protocol in the AVRISP project.
16 years ago
Dean Camera f3e4fbe512 Use the PDI REPEAT instruction in the PDI programmer code to reduce protocol overhead and greatly improve transfer throughput. Switch bit-bang USART in the AVRISP project to Timer 1, so that Timer 0 can be used for hardware timeouts while waiting for the NVM bus or controller to become ready.
16 years ago
Dean Camera 1fa27139f5 Split out NVM access code in the AVRISP project into a seperate NVMTarget.c source file and header. Make NVM register accesses use the NVM base address as set by the host, rather than using the fixed value from the XMEGA datasheet.
16 years ago
Dean Camera 3705330dd3 Use -pedantic compile time option to find and correct several minor code errors.
16 years ago
Dean Camera 307ba254d5 The AVRISP project can now enter PDI mode under both bit-bang and hardware USART connection modes, tested against the XPLAIN board hardware. Still need to complete higher level NVM access code so that the device's memories can be read and written.
16 years ago
Dean Camera 33a46b243a PDI NVM enable is fast enough that bare polling is enough without a fixed delay in between each attempt. Make sure the USART transmitter is enabled explicitly when the USART is configured, so that repeated attempts to re-enter PDI mode don't fail due to TXEN not being set.
16 years ago
Dean Camera 66201a05e9 Fix PDI code - must send NVM enable key least significant byte first, need to make sure Tx and Rx is switched correctly including disabling the output on the Tx line when receiving.
16 years ago
Dean Camera 7e5966c1a8 Fix AVRISP PDI protocol - make sure inverted masks have the appropriate parenthesis around them, make sure the BREAK command for the hardware USART has 12 clock cycles exactly. Poll NVM Enable bit in the target's STATUS PDI register with a timeout, as it is not set immediately.
16 years ago
Dean Camera 42cfd15793 Change over AVRISP project to have both hardware USART and software USART modes for the PDI protocol, when enabled. Fix up PDI initialisation routines.
16 years ago

16 years ago
Dean Camera 1e3513ed70 Add even parity bit to the software USART framing in the AVRISP project's PDI programming code.
16 years ago
Dean Camera 9c8ed168e5 Fix inverted bit-banged USART logic in the AVRISP project for PDI programming. Add a delay to the clock toggling in the AVRISP project to ensure that the programming speed does not exceed 10MHz under any conditions to satisfy the limits in the datasheet for all target voltages. Fix incorrect pin being used as the DATA in in PDI programming mode.

Dean Camera 258a6a0177 Fix the tokens which enable and disable the different programming protocols in the AVRISP project.
