Shouldn’t it be as follows? #define CONFIG_LV_TICK_CUSTOM_SYS_TIME_EXPR (long)esp_timer_get_time()/1000 The generated line in sdkconfig.h is #define CONFIG_LV_TICK_CUSTOM_SYS_TIME_EXPR "(long)esp_timer_get_time()/1000" Hal settings in sdkconfig are: #ĬONFIG_LV_TICK_CUSTOM_INCLUDE="esp_timer.h"ĬONFIG_LV_TICK_CUSTOM_SYS_TIME_EXPR="(long)esp_timer_get_time()/1000" I set the HAL values using menuconfig in lvlg component menu. I’d like to set a custom tick function but the define generated refers to a string, not to the function itself. As an example, you can change the character used to create the progress bar with the char argument, but type ?pboptions for additional arguments and details.How to set a custom tick source function What MCU/Processor/Board and compiler are you using?ĮSP32/VScode/PlatformIO What LVGL version are you using? There are several arguments that you can customize. The possible values are "timer" (default), which displays a progress bar with the estimated remaining and elapsed times, "txt", which removes the timing, "win", which sets a Windows progress bar, "tk" for a Tk progress bar and "none", to avoid displaying the bar. In addition, you can also customize the type of progress bar displayed with the type argument of the pboptions function. Sys.sleep(1) # Remove this lines and add your code In the following block of code we show you an example using the pblapply function, but all functions provide the same functionality. The package provides the pbapply, pblapply, pbsapply, pbtapply, pbmapply and pbreplicate functions. In the previous section we reviewed how to add progress bars to for loops, so in this section we will discuss how to use the pbapply package, which adds progress bars to the apply family functions. Progress bar with apply functions: ‘pbapply’ package SetWinProgressBar(pb, i, label = pctg) # The label will override the label set on the Label = "Percentage completed", # Window label Pb <- winProgressBar(title = "Windows progress bar", # Window title Note that if you specify a label or a title on the setWinProgressBar function, it will override the corresponding arguments of the winProgressBar function. The process for adding it is analogous to the previous examples, but in this case you can also add a title and a label. However, if preferred, you can also create a Windows-style progress bar with the winProgressBar and setWinProgressBar functions. In the previous sections we show how to create text progress bars, which will be printed in the console. Windows progress bar with winProgressBar function Sys.sleep(0.1) # Remove this line and add your code There are several arguments that you can customize, so recall to type ?progress for additional details, but the most relevant is the format argument, which allows formatting the progress bar as desired, with different types of configurations.Ī complete example is shown in the following block of code, with a spinner, the bar, the completed percentage, the elapsed time and the estimated remaining time: # install.packages("progress")Ĭlear = FALSE, # If TRUE, clears the bar when finish # install.packages("lubridate")Īs an alternative to the previous functions you can use the progress package, which allows further customization. Note that in order to display hours, minutes and seconds we have used the seconds_to_period function from the lubridate package. In order to provide further functionalities, we have developed an approach to display the elapsed time and an estimation of the remaining time, based on the mean time that the previous iterations took to run. The function only displays the current percentage of iterations that have been executed. In the following block of code we show you how to set a progress bar inside a for loop, briefly describing the different arguments that you can customize. The most common functions used to add a progress bar in R are the txtProgressBar and setTxtProgressBar functions from R base. Insert progress bar The txtProgressBar function 3 Package ‘beepr’: sound notification when code execution ends.2 Progress bar with apply functions: ‘pbapply’ package.1.4 Tk progress bar (Unix-alike) with the tkProgressBar function.1.3 Windows progress bar with winProgressBar function.1.1.1 Elapsed and estimated remaining time.
