Included with Tollos is some source code (in directories named ‘public’) which is not Tollos source code and which may be covered by other licences. You should read those before re-distributing that code.


Tollos is distributed as a compressed .zip file. Here is the latest version:

Changes list

(Click on the version number for the corresponding .zip.)
2012.02.19 1.26 sysSet(SYS_WATCHDOG, value) was rejecting valid settings due to a change in 1.25
2012.02.09 1.25 Several improvements to timing, allowing SysTicks and tick() of less than 1 ms; also SysTick priority is now preserved when SysTick timing is changed (previously it was set to the lowest interrupt priority by the ARM library).
2012.01.12 1.24 Improved gyroscope and accelerometer handling:

gyroRate, accRange, and accRate now return chosen value (instead of 0) when successful

tollosAcc and tollosGyro now use a ring buffer rather than double-buffering to allow accurate integration of results and detection of overrrun.

2011.11.18 1.23 Added i2cGetByte and i2cPutByte functions; drawOval renamed to drawEllipse
2011.10.09 1.22 Cosmetic tweaks and commentary improvements
2011.01.27 1.21 Added miniDec decimal package to Tollos; more strf string formatter enhancements
2011.01.16 1.19 Added gyroscope functions and ITG3200 device support; improved strf string formatter
2011.01.08 1.18 Added drawing functions and DOGXL LCD screen support, including:

– graphics functions (lines, box, ellipse, simple polygon fill)

– formatted string and text support

– proportional and monospace fonts

– 3-wire 9-bit SPI support for LPC17xx

2010.12.20 1.17 Added vector priorities and USB/Virtual COM port support for STM32
2010.12.14 1.16 Added I2C support for STM32 and improved STM32 peripherals clocking
2010.12.12 1.15 Added support for some STM32 controllers and Primer2 board, including

– improvements to link scripts; configuration at board level

– new variable-speed startup code for all microcontrollers

– additional BIT_OPENDRAIN option for bit output

– sample and getting started page for Primer2.

2010.12.05 1.13 Corrected error in NXP I2C_SetClock function which caused I2C channel 2 clock to run twice as fast as specified (see FAQ).
2010.12.03 1.12 (Initial release.)
